Clinical Observation on Silicone Intubation in Obstruction of lacrimal Drainage System

ABSTRACT

We report 23 cases of silicone stents intubation for obstruction of lacrimal drainage system in 23 patients with tearing and mucopurulent material discharge from January 1985 to April 1988. The success rate of silicone stents intubation was 47.4% and the most common site of obstruction was nasolacrimal duct(56.5%). 30.3% of patients had complications related to silicone stents, conjunctivitis, punctal erosion etc. With these results, we consider that congenital dacryostenosis, partical and complete nasolacrimal duct obstruction is mainly indicated for silicone stents intubation and better results will be gained if be done with acryocystorhinostomy to prevent complications related to silicone stents.
